Flat objects made of peripheral material, e.g. plates or hangers with a small gap, the powdery material is subjected to a pressure between the two stamps located in the die body. This requires a drive mechanism to control both punches. The mutual control of both stamps should be coordinated very well in order to obtain a desired press between the stamps during pressing. Especially with a press for manufacturing; There are no difficulties with very small objects. With frequent use, there is further wear and tear on the parts of the highest pressing pressure in the first die preform tv pellet then the worn area; ird which Timm a ~ rösseren DurehscLnitt than the rest of the luatrize occurs when ejecting the compact easily break on 3s itt-lenn. .uch notv / endif "^ ie L '. ^r - ~ trize durci: replace a new su.

Excessive material in the atric space sinks slightly. The cam 7 then acts on the lever 15 , so that the pin 36 moves upwards until its upper end is again aligned with the upper side of the die. The further movement of the slide, the lower punch and the rtift can again be the same as that described above. It can also be useful for a good filling of a very small matrix space, when using a third lever that can be pivoted around the pin 11, to form the associated tease in such a way that the lower punch first sinks so far that the I.
